gathering info from listbox..

[chelnov63]

How i was just wondering, how do I gather the info selected in a list box on the php page to which the form is submitted..

 

e.g the form is:

 

<form action="add_contact.php" method="post">
<SELECT name = "contacts" MULTIPLE SIZE=5 >
<OPTION VALUE="o1">Option 1
<OPTION VALUE="o2">Option 2
<OPTION VALUE="o3">Option 3
<OPTION VALUE="o4">Option 4
<OPTION VALUE="o5">Option 5
<OPTION VALUE="o6">Option 6
</SELECT>
</form>

 

How would I gather which values were selected when the form is submitted..thanks in advance

I've tried doing:

 

<?php

      $values = $_POST['contacts'];

        foreach($values as $key)
	{
          echo $key."<br>";
       }

   ?>

 

however I get the error:

 

Warning: Invalid argument supplied for foreach() in C:\htdocs\ABC\ on line 7

got it name="contacts" should be name = "contacts[]"
